Hi everybody,
I have implemented a inbound interface to take over vendors by Idoc type CREMAS (basic type CREMAS05).
So from time to time we have the problem that some values in the target system will be overwritten by the processed IDoc because the field is empty. Some of these cases I have already handled by setting the no_data_sign (/) inside a user exit.
But now I want to do this for all emtpy fields (and segments) to be sure that in future this problem occurs not again.
My idea is to do this also inside the user exit by an dynamic look and dynamic assigment of the segment structure itself.
So each field which is empty will be filled with the no_data_sign.
So now I have some questions/problems:
1.) If really a empty field will be transfered I can not indicate this case. So is it better to do it by a conversion rule instead of a user exit?
2.) Can I mapp inside a conversion rule the source value to taget value and additional the no_data_sign as fallback? Does andybody know if this working?
3.) Is there a default function module to fill up empty idoc fields with the no_data_sign?
Regards and thanks in advance
