Message no. FH056
You are trying to create a G/L account for which a secondary cost element has probably already been created. If this is the case, it is not possible to create a G/L account for the same number.
The program cannot create a G/L account with this number.
Check the G/L account number used, and change it if necessary.
If the G/L account number is correct, check whether a cost element has already been created with the same number and check which cost element category has been used. You may need to use new numbers here. If the existing cost element is a primary cost element type, then the status of the relevant tables is incorrect because primary cost elements can only be created with G/L accounts that already exist.
This is the error, we are facing while creating a GL on COA lavel.
Please help us with the valuable input, If any.
