Display account distribution on expense item at Expense report.

Hello,

I'm trying to watch, change and modify the account distribution in a user when it's doing an expense report. In another user with the same legal entity, same BU, and same templates, the application shows me at the level item in the expense module the account distribution and I can modify it, but not in the other that I want.

I already ran the Run Diagnostic Test and it showed me the error:

"The operation to create a new account code combination id failed. The error message has to be interpreted in order to determine what action can be taken. It could be a cross validation rule or that the account is a summary account or something else."
