Requirement

Replicate a material type for example MAT_YYYY into CRM system without using middleware.

After replication, the generated category could be used in normal product scenario ( for example, create new product based on this category, read / query operation on this category etc )

I have successfully written a API which could replicate data ( to simulate T134 ) into CRM category table.

Once this API is executed, a new category will be created in CRM system, without middleware.

This category could be found in tcode COMM_HIERARCHY:

Unfortunately, it is not visible in product creation page 😦

bug fixed now. POC is done.

Run method in SE24, specify new product category id via parameter iv_cat_id:

Execute method, ensure ev_success equals to abap_true.

Once created, the category could be searched via tcode COMM_HIERARCHY:

And the category could be used to create new product in WebUI:
