How to download BOM from ERP to CRM

(1) In ERP, create one material 1468 "JVM":

And another material 1469 "JDK 1.8":

(2) Create BOM via tcode CS01 based on material 1468 with the following settings:

Add 1469 as line item:

Once saved, there is one entry generated in table MAST:

 

(3) Create one download request in CRM via tcode R3AR2:

 

Specify MATNR to the material id of BOM header:

 

After I perform request download via this request, in WebUI I found that the assignment block "Components" is still empty.

The reason is the dependent material 1469 is not downloaded to CRM yet.

(4) Then I first download material 1469 to CRM, and then I perform request download again via the request created in step 3.

After that in tcode SMW01 I can see necessary data for BOM structure, the relationship STRSET, is successfully downloaded.

Now go back to WebUI, I can see the expected component structure as displayed below.

BOM, MAST, CS01, STRSET, MATNR
