Creating documentary batches programmatically with BAPI_GOODSMVT_CREATE? - abap

Question

Summary of the problem
Automatic Documentary Batch handling through custom ABAP code
My employer wishes to perform automatic documentary batch handling on some products from external vendors, and I'm trying to figure out how to set this up through Customizing and ABAP.
It seems to me that Documentary Batches are only meant to be used through MIGO - in any case I'm unable to find a proper solution to assign them programatically, and any hacked-together solution I can come up with, seems insufficient and unstable.
What avenues do I have to solve this issue?
Enhancing BAPI_GOODSMVT_CREATE?
Can I somehow do it through stuff like BAPI_GOODSMVT_CREATE?
Enhancing PPPI Message Destinations?
I also specifically need it to work for consumption messaging through PPPI, and I thought to build on top of the standard Message Destination PI04, FM COCI_CONFIRM_MATERIAL_CONS.
This FM creates a Material Document but does not go through the BAPI_GOODSMVT_CREATE FM.
It does however use MB_CREATE_GOODS_MOVEMENT.
What I've already tried
MIGO Snapshot based Single Use hack solution
I made hack-solution for one area, where I watched which table-updates MIGO performed and with which data (through FM's VB_INSERT_BATCH and VB_BATCH_WHERE_USED_LIST), and then filled out these structures manually.
However, providing all the needed info is not feasible for other implementation areas, as they do not have all the necessary values available, and it doesn't cover unforeseen situations where other parameters might be required.
Reading through BAPI_GOODSMVT_CREATE code
I've tried spying on whether BAPI_GOODSMVT_CREATE performs the same FM's but only found it accessing VB_BATCH_WHERE_USED_LIST.
It seems to be possible to activate this functionality by controlling Memory ID Documentary Batch #1, Documentary Batch #2, Documentary Batch #3 and Documentary Batch #5 (see FM VBDBDM_DATA_POST_IM), but this requires filling out a lot data, including the structure named DOCUBATCH_SCREEN_FIELDS, which again makes it seem like this might not be the correct avenue of approach.
Regardless, this still doesn't allow me to maintain batch through tables MCHA and MCH1.
Hacked together solution based on MIGO snapshot
Here is how my hacked solution looks. Again, this is not a feasible way to go about the problem, as other implementation areas does not have the resulting Material Document immediately available:

Why this isn't good enough, and what I need
This performs as a snapshot of MIGO configured with documentary batch handling, but doesn't necessarily cover all cases.
It only works in the context of a Purchase Document, and doesn't cover other cases such as Orders and Sales Orders.
Additionally I only have the necessary date because of the material document being created immediately above, which is not possible for all implementation cases.
I would like to know if there is an intended way to perform Documentary Batch handling from custom code.

Answer 1

Quoting from the documentation:
If you work with RFID or TRM functions, or call IDocs/BAPIs, you can only book in documentary
batches by calling up the RFC-capable function module VBDBDM_DATA_MAINTAIN_RFC
beforehand or incorporating it into the process.
So maybe this function module is the key?
However, it seems you may not be the first to experience this pain. A comment on that documentation reads:
Documentary Batch has a lot of constraints and it seems to be a semifinished product of SAP, since is missing a lot of features of real batches.
Be prepared to make a lot of custom enhancements...
