Posting Journal- Balance Constraint not aligned with Consolidation Rule

Current Challenge: Troubleshooting/ tracking the data is nightmare

Root Cause: When a user create a manual journal entry and try to post the journal system throws error message "Invalid" with balance constraint "Legal Entity" and allows to post even with the invalid message. There is no possibility to change the balance constraint to "Journal Entry" in the posting journal web report whereas if user upload the journals via excel system accept and post the journal without any error message by keeping the balance constraint as "Journal Entry".

Please note that while performing consolidation rule, the balance constrain can be selected through the combo box- member "PJ Constraint".

Suggestion by Consultants: Will it make sense to have the combo box to select the balance constrain in the posting journal template- similar to consolidation rule.
