Request clarification before answering.
Hello Christoph,
Just for information - A:ORD means Instance administration data that is ESTVA, L:ORD means Composition that is ESTVP. Both are related with one another as shown below

I aggree when you are loading composition data into difference instances like one with Public with REG_WORLD and another one with Public with REG_WORLD.But when you load into the same instance it becomes optional, system will load the into the same instance all the components. Though your suggested approach is good to avoid any issues.
Now coming to the Usages being declared twice, it is a typo. Even then system will not generate two instances of the compositions because we have declared L:ORD at the beginning and it has preceedance in the structure definition. However while writing the Usage to the record system might find data is already available and will give an error that “Record already available” and it will not write any data and usage data becomes blank.
Thanks and Regards

Dear Jayakumar
we are now 100% aligned. But coming back to detail: what wil happen in system if you do not define "COMPREL" value?
COMPREL (and concentration) to gether are "key facts" to differentiate property of type "B" or C". Do you know OCC approach here? What will happen wiout comprel (as in this example)? I would assume: it will be "empty" (but this would be not good). Do you know: is OCC checking (in upload) the "type" of property? What means. If you prepare data as for type "C" but property is of type "B" (you have prepared wrong content) => what will happen? Error message?
C.B.
Hello Christoph,
COMPREL is a mandatory field and if reference quantity is not defined then the load will fail; in the above example system picks the COMPREL based on the reference unit we defined for the component like pc or %.
For Substance listing load the Character Type is "L" but the Field is not COMPAVG, instead it is something like REFSUBTR, so it would be different format and system will not automatically create a listing for a composition type like VA type B or C. if you mistakenly put a wrong data then if you do not declare Unit or value it will fail to load.
Thanks and Regards
