How make the error message M8108 as warning
Could any one please let me know if i can change the error message "M8 108, Check if the invoice is already posted under the document No:" to warning message. So that the end users can go ahead with the posting even when the warning message is shown.
When we post an invoice and reverse the invoice due to some reasons and again try to repost the invoice with same datails then the system is giving that message and we are unable to post the invoice. Then we have to add a character in the reference field so then the system is able to post the invoice.
I Have tried to change the error message to warning under the transaction code oba5 and sm31 (table v-t100c) but the system is not able to change and i am still getting the same error. Could anyone please let me know what needs to be done. Do i need to change the standard program with the help of ABAPer, if so what will be the impact.
