2630333 - Error:Posting date should not be less than DD.MM.YY, Not later than todays date

when you post or approve a supplier invoice where buying company is in Italy, you may get this error.

SAP Business ByDesign

Currently we have a legal requirement in Italy to have a sequence in the way invoices are posted based on posting date of invoice and thus we have developed system accordingly.

Explanation of system behavior with an example is given below:

Say last invoice posted in customer system is A with posting date as 18.3.2018 and today's date is 21.3.2018.
Now customer created two invoices later one Called B with 19.3.2018 and another Called C with 20.3.2018.

Case 1:

Both invoices B and C went for approval and approver first approves C and it gets approved successfully cause system checks based on last posted invoice posting date and in this case it is 18.3.2018, Now when he tries to approve B he gets error: Posting date should not be less than 20.03.2018, Not later than today’s date.

Case 2:

Both invoices B and C are just saved (no approval is there in this case)
If customer first posted the invoice C it gets successfully posted cause system checks based on last posted invoice posting date and in this case it is 18.3.2018, Now when he tries to post B he gets error: Posting date should not be less than 20.03.2018, Not later than today’s date.

Note: A,B,C are Supplier invoice IDs
