To change a GL transaction that was created in a BPS batch (example BP4 batch) you will go to BPS Budget Transaction Menu > Budget Transaction Changes. Enter the appropriate transaction year (2016) and Budget ID (2), filling in the GL account you will see all the transactions that have been posted to that account, you can then modify or delete the applicable transaction.
You can also find your transactions by searching by batch and transaction number.
Accept the transaction information and it will then ask you for the document number of the transaction, this is the number in the batch listing.
You can find this information by running a transaction report by batch, BPS Budget Transaction Menu > Budget Reporting > Transaction Report by Batch
You can make changes in the transaction batch and it will make the adjustment in the transaction. As an example, in Transaction changes, you can change Field 03, or Field 04 and it will make the calculation change for that transaction.
If you changed Field 03 = Unit Quantity to 2.0 then the batch transaction would make the calculation of 2 x Field 04 of $36,873.00 and would change Field 05 = Amount to $ 73,746.00
If you run into the error "Error reading Original Budget Summary. Msg: ? Record not found Update of Budget Summary not completed" when checking a transaction, you can just enter through the Fields and if you do this twice, the error goes away.
