Summary :
When posting or altering a sales order in SAP, a short dump with the message 'Type conflict when calling a function module' may occur. This is caused by a program error, specifically following the implementation of SAP Note 645021. The error arises due to a type mismatch at the function module interface under "I_RFPOS", where "U_RFPOS" contains a different field type. The solution to resolve this issue involves implementing the correction instructions provided in the note to rectify the type conflict and prevent the dump.
