Problem with BOM (packaging material) in order change

Question

Hi Gurus,
In my b2b shop, i have created an order with BOM material and that order contains one main material and a sub item material after update or order. When i open the same order and click on change, when i click on update, a new sub item is getting added as a main item.
Details:
item 10 is 12007492 (main material)
item 20 is 12007491(sub item for the main material)
when i click on update,again one more sub item 30 is getting added.
When i check the logs, all the items guids are getting passed to IN of crm_isa_basket_changeitems functions module. But when check it in runtime using external debuggin mode, the sub item guid is blank.
Then the main material is again getting exploded and the sub item is coming at item 20 and actual sub item before update is shifting to item 30 as new item.
Please help me in this regard why it is happening like this.
Thank you
Lakshman

Hello Lakshman,
I had the same issue, however my backend system was ERP and not CRM. In any case, the logic might be the same.
When a BOM material is sent to the backend system for simulation/save, only the header needs to be sent. By this, backend system will explode the material and send 2 items back. I guess in your case, ISA is sending both items to SAP and that is the reason you are getting back 3 items.
Simplest approach is to write some logic in your backend class to avoid sending this subitem to SAP. You can achieve this by manupulating the items table sent to SAP
Suppose salesDoc is the ISA document and itemsTable is the JCO table that is sent to SAP as a table parameter:
               ItemList itemList = salesDoc.getItems();
               for (Iterator iter = itemList.iterator(); iter.hasNext();) {
                    ItemSalesDoc itemSalesDoc = (ItemSalesDoc) iter.next();
                    TechKey parentKey = itemSalesDoc.getParentId();
                    if(null!=parentKey){
                         if (!parentKey.getIdAsString().equalsIgnoreCase("")) {
                            //Here remove it from the tables parameter which is sent to SAP
                                           itemsTable.deleteRow(i);
I am not too sure how it would work for CRM, but works in ERP.
