Expert-Routine: No transformation
when defining 'normal' transformations, you've got the possiblity to define which fields of the target-structure shall be modifed or stay untoched (by using the option "No transformation"). This allows for example to load master-data attributes from several sources, while every source only needs to provide a subset of all target-fields.
I'm looking for something similar in conclusion with the expert-routine.
Is there a way to write an expert routine which only updates e.g. target-field 1,2,3,7 while 4,5,6 are not modified at all?
Please note that writing a _SPACE_ to any of the not wanted target-fields will erase the already existing value in the master-data-tables.
Hence transfering _SPACE_ into this fields is certainly not solution I'm looking for.
In other words: Is it possible to reduce the target-structure in an expert-routine without changing the target itself?
Thanks for your hints,
