Unable to switch back the ATO model from Buy to MAKE

Hello Everyone,

Initially our ATO mode (along with its option class and components) is set to MAKE type. When SO is created it will progress to Production open status.

Now, we have the requirement to switch this ATO model from MAKE to BUY. Also, make sure all the existing ATO configuration item also switches from MAKE to BUY.

So what I did was change a few attributes in the ATO model, they are:

1) Purchase flag

2) Purchase enabled flag

3) Planning make and buy code to BUY

Ran the "Update existing configuration" program with the parameters:

1) For specific configuration

2) Has sourcing changed? Yes
