Reproducing the Issue
Go to the Tax Management Work Center.
Select VAT Entries.
Click on New Tax Entry
Result: In the drop down G/L account, you notice that the G/L account XXX(XXX represents the G/L account ID) is not available for selection.
The G/L accounts available to choose in the drop down are not GL Accounts, they are in fact GL Account Groups. These are defined in Business Configuration Activity Charts of Accounts, Financial Reporting Structures, Account Determination->Edit Account Determination Groups. Only the groups defined under General Ledger can be used if they have the indicator Available in Other Transactions checked.
Per your business needs, make available the G/L account group required by marking them as Available in Other Transactions.
