Dynamics GP Project Error

This article addresses common errors encountered in Microsoft Dynamics GP when attempting to input negative quantities or process returns for projects. These errors typically arise from the system’s built-in safeguards to prevent negative balances in project accounting. Understanding the causes and resolutions for these errors is crucial for maintaining accurate project costing and revenue tracking within Dynamics GP.

Symptom: Encountering Error Messages

Users may face various error messages when trying to enter negative quantities or returns in project-related transactions. These errors are designed to prevent unintended negative values in key project metrics. Below are some typical error messages you might encounter:

  • “You are not allowed to have negative Actual Quantity.”
  • “You are not allowed to have negative Actual Costs.”
  • “You are not allowed to have negative Actual Accrued Revenues.”
  • “You are not allowed to have negative Total Revenue for the Cost Category within the Budget.”
  • “You are not allowed return accrued revenues greater than the actual posted amount.”
  • “You are not allowed to return a quantity greater than the actual posted quantity.”
  • “You are not allowed to return costs greater than the actual posted amount.”

These errors can appear in several transaction entry windows within Dynamics GP, including:

  • Timesheet Entry
  • Employee Expense Entry
  • Equipment Log Entry
  • Inventory Transfer Entry
  • Returns from Project Entry
  • Returns Transaction Entry

It’s important to note that these messages are triggered by the system’s validation rules to maintain data integrity in your project accounting.

Cause: Project Accounting Logic and Data Validation

The root cause of these errors lies in the core logic of Dynamics GP Project Accounting. When a negative cost transaction or a return is entered, the system performs a crucial validation check. It examines previously posted transactions against the specific project and cost category to determine if the new transaction would result in a negative posted amount. This check is conducted across three critical areas: Quantity, Cost, and Revenues.

Dynamics GP will only allow the transaction to proceed if, after applying the negative entry or return, all three values (Quantity, Cost, and Revenues) remain at zero or above for the project and cost category. This validation mechanism is in place to ensure the financial accuracy and integrity of project data.

Data Points and Calculation

The system relies on the PA01301 (Project Budget Master) table to perform this validation. Specific fields within this table are reviewed for each of the three areas:

  • Quantity: The system aggregates values from PAPostedQty (Posted Quantity) and PAUnpostedQty (Unposted Quantity).
  • Cost: The system sums values from PAPostedTotalCostN (Posted Total Cost) and PAUnpostedTotalCostN (Unposted Total Cost).
  • Revenues: The system calculates the sum of PAPosted_Accr_RevN (Posted Accrued Revenues) and PAUnpostAccrRevN (Unposted Accrued Revenues).

Example Scenario:

Imagine a scenario where you initially posted a timesheet for 8 hours against a project. In the PA01301 table, PAPostedQty would be 8. Later, you need to correct this and enter a timesheet for -2 hours to reverse a portion of the original entry. This -2 hour transaction is saved in a batch, updating PAUnpostedQty to -2.

Now, if you attempt to enter another timesheet for -6 hours, the system performs the calculation: 8 (Posted) + (-2) (Unposted) + (-6) (Current Entry) = 0. Since the resulting quantity is zero, the transaction is allowed. However, if you tried to enter -7 hours instead, the calculation would be 8 + (-2) + (-7) = -1, resulting in a negative quantity, and the system would trigger the error message and prevent the entry.

This same calculation principle applies to both Cost and Revenue fields, ensuring consistent validation across all three key metrics.

Exception: Miscellaneous Log Cost Category

It’s important to note a specific exception to this rule. Cost category types classified as Miscellaneous Log are permitted to have negative values for actual posted Quantity, Cost, and Revenues. This exception is designed to accommodate specific scenarios where negative adjustments are valid and necessary for miscellaneous project expenses. For all other cost category types, the system strictly enforces the non-negative balance rule.

Resolution: Steps to Address Negative Quantity Errors

When you encounter these errors, the primary goal is to identify and correct the underlying data discrepancies that are causing the system to prevent negative entries or returns. Here’s a step-by-step resolution process:

1. Review Budget Detail Entry Window

The first step is to examine the Budget Detail Entry window within Dynamics GP. This window provides a summarized view of the actual quantities and costs posted against a project and cost category.

Navigation:

  1. Go to the Cards menu.
  2. Point to Project.
  3. Select Project.
  4. Enter the relevant Project Number.
  5. Click Budget.
  6. Highlight the specific cost category in question.
  7. Click the expansion arrow next to the Cost Category ID field.

In the Budget Detail Entry window, review the Actual row. Pay close attention to the displayed values for Qty and Total Cost. These values represent the summarized posted and unposted amounts that the system is using for its negative quantity/cost validation.

To investigate the details behind these summary values, click the Actual link. This will drill down to the associated cost transaction inquiry window, providing a detailed breakdown of the transactions contributing to the summarized figures. Analyzing these detailed transactions can help identify any discrepancies or unexpected entries.

2. Run SQL Script to Verify Table Values

For a more direct examination of the data, you can execute a SQL script against the Dynamics GP database. This script queries the PA01301 table, allowing you to directly view the values in the fields used for the negative quantity/cost validation.

SQL Script:

SELECT PAUnpostedQty, PAPostedQty, PAUnpostedTotalCostN, PAPostedTotalCostN, PAUnpostAccrRevN, PAPosted_Accr_RevN, *
FROM PA01301
WHERE PAPROJNUMBER = 'XXX'  -- Replace 'XXX' with your Project Number
  AND PACOSTCATID = 'YYY'  -- Replace 'YYY' with your Cost Category ID

How to use the script:

  1. Open SQL Server Management Studio or your preferred SQL query tool.
  2. Connect to your Dynamics GP database.
  3. Replace 'XXX' with the actual Project Number and 'YYY' with the Cost Category ID you are investigating.
  4. Execute the script.

The results will display the values of PAUnpostedQty, PAPostedQty, PAUnpostedTotalCostN, PAPostedTotalCostN, PAUnpostAccrRevN, and PAPosted_Accr_RevN for the specified project and cost category. Compare these values to the summary values observed in the Budget Detail Entry window and the detailed transactions in the inquiry window. Discrepancies may indicate data synchronization issues.

3. Execute PA Reconcile on Cost Transactions

If you suspect that the summary values in the PA01301 table are not accurately reflecting the underlying detail transactions, running PA Reconcile is the next crucial step. PA Reconcile is a utility within Dynamics GP Project Accounting designed to synchronize summary and detail data.

Navigation to PA Reconcile:

  1. On the Microsoft Dynamics GP menu, point to Tools.
  2. Point to Utilities.
  3. Point to Project.
  4. Select PA Reconcile.

In the PA Reconcile window, select Cost Transactions for the Reconcile Type. Specify the relevant Customer ID associated with the project. Running PA Reconcile will recalculate and update the summary values in the PA01301 table based on the detailed cost transactions. After running PA Reconcile, re-examine the Budget Detail Entry window and rerun the SQL script to see if the values have been corrected and if the error is resolved.

4. Check for Orphaned Unposted Transactions

If PA Reconcile does not resolve the issue, the next step is to investigate for potential orphaned or stranded unposted transactions in the Project Accounting work transaction tables. These tables temporarily store transactions before they are fully posted. If transactions are interrupted or not processed correctly, they can become orphaned and lead to data inconsistencies.

Work Transaction Tables to Check:

  • Timesheets: PA10001
  • Employee Expenses: PA10501
  • Equipment Logs: PA10101
  • Purchase Materials: PA10901 and PA10702
  • Inventory: PA10901

Procedure:

  1. Use SQL Server Management Studio or your SQL query tool.
  2. Query each of the work transaction tables listed above. For example: SELECT * FROM PA10001 WHERE ... (You may need to add WHERE clauses to filter by project or date range to narrow down the search).
  3. Look for any transactions that appear to be incomplete, stuck, or dated incorrectly. Orphaned transactions often lack corresponding entries in the posted transaction tables.

If you identify stranded records, it’s generally recommended to remove them from the work tables. Caution: Exercise extreme care when deleting records directly from SQL tables. Always back up your database before performing any direct data manipulation. Consult with a Dynamics GP expert if you are unsure about identifying or removing orphaned transactions.

After removing any stranded records, run PA Reconcile on Cost Transactions again. This will ensure that the system recalculates the summary values without the influence of the orphaned transactions. Re-test your negative quantity or return entry to see if the error is resolved.

More Information: Advanced Troubleshooting

If the previous steps do not resolve the negative quantity error, and you’ve confirmed that PA Reconcile has been run and no orphaned transactions are present, it’s possible that there is an underlying issue with the posted cost transactions themselves.

Review Posted Cost Transactions

In this scenario, the PA01301 table might not be accurately reflecting the actual posted quantity, cost, or revenue when compared to the detail transactions. This could indicate data corruption or inconsistencies in the posted transaction data.

Posted Cost Transaction Tables:

  • Timesheets: PA30101
  • Employee Expenses: PA30501
  • Equipment Logs: PA30201
  • Purchase Materials: PA30901 and PA31102
  • Inventory: PA30901

Troubleshooting Steps:

  1. Examine Cost Transactions: Review the posted cost transactions in the relevant tables for the project and cost category in question. Look for any abnormalities, such as incorrect quantities, costs, dates, or other unusual data.

  2. Consider History Removal and Re-entry: If you identify problematic posted transactions and are confident in the correct data, consider removing the historical transactions and re-entering them. Important: Removing history is a significant action that should only be taken with caution and proper backups. Understand the implications of removing historical data before proceeding.

  3. Purchase Materials Transaction Note: If you are working with purchase materials transactions, specifically verify the ORD field in the PA31102 table. This field indicates whether the receipt originated from a purchase order.

    • If the receipt was from a purchase order (the PApurordnum field is populated), the ORD field should be populated with a value other than 0.
    • If no purchase order was involved, the ORD field should be 0.

    If the ORD field is incorrect, update it to the correct value using a SQL UPDATE statement. After correcting the ORD field, re-run PA Reconcile on Cost Transactions. Incorrect ORD values in purchase materials transactions can sometimes lead to data discrepancies and negative quantity errors.

By systematically following these resolution steps, you should be able to diagnose and correct the Dynamics GP Project errors preventing negative quantity entries and returns. Remember to proceed cautiously when working with SQL queries and data modification, and always back up your database before making significant changes.
