Failed to update in the Item Master Form ATO field checked

Question

Hi All ,
I am trying to implement B2B ( Back to Back Order ) and to implement the B2B the ATO should be checked irrespective of Manufacturing is installed or not.
Now the problem is I am able to update some of the item but failed to update some of the item and it gives error " the Sales Order Line is opened you can not
check the ATO".
Now I did to avoid this I updated the columns BUILD_IN_WIP_FLAG to 'Y' and REPLENISH_TO_ORDER_FLAG = 'Y' in the Item master table .
And I was successfully able made further transaction of the open sales order line.
I wanted to know to updating the field BUILD_IN_WIP_FLAG to 'Y' and REPLENISH_TO_ORDER_FLAG = 'Y' will impact our bussiness in Future.
Regards,
Sharad

Hello Sharad,
First thing, if you are implementing B2B in your system then your organization is a Manufacturing organization or distribution organization?
If this is not a Manufacturing organization, then the item should be a Buy Item along with ATO attribute enabled. So that the B2B requisition created & then PO.
If you are implementing Assemble to Order in Manufacturing organization, then your ordered item should be a make item not a buy item. For this sub assembly or finally assembly you need to define the bill, routing etc. After that once you book the ATO sales order, the work order will be created. & the process continues.
The error "the Sales Order Line is opened you cannot check the ATO", comes when you are having open sales order exists & you are trying to update item attributes. It is always advisable to close all the sales order lines in this case before changing the same.
Unless & until you are using BOM & WIP in your organization, change of BUILD_IN_WIP_FLAG will not affect. Please make sure not to update these attributes from backend using database update script.
