Product A001 has a default Account Assignment Group of X6. G/L account 41007100 by default is assigned to X6.

Project Billing only checks against G/L accounts maintained under Cost Element Group YBPS_R030 for On-Account Issued. G/L account 41007100 should be assigned to YBPS_R030.

Check in app Display Line Items in General Ledger that the Invoice was posted against 41007100. If not, then correct the above configuration.
