KNA1 Mass Maintenance with a BADI implemented.
We have implemented a Customer Master BADI to maintain some additional KNA1 and KNVV fields.
when we execute XD99 to mass maintain an SAP field (KNVV-AUFSD)we receive an error "Enter a valid value". When I debug I dsicover that it is attempting to update the extra fields from the BADI using a value of '/' which is usually the null value even though I have not and can not select these fields for update.
Has any one encountered this problem before?
Thank you in advance.
