BRF+ and DDIC

[former_member277448]

hello

we have built an application that has a context bound to a DDIC structure.

In the past we have had the need to change some of the properties of the data elements and domains in the DDIC.

Sometimes when we did this things went fine.

Sometimes when we did this links got broken and we had to spend a considerable amount of time rebinding data objects to data elements.

it is not clear to me what things it is safe to change in DDIC and what it is not.

For example,

• is it safe to change a data elements type from (say) a CHAR to a NUMC?
• is it safe to change the length of a CHAR data element?
• is it safe to move a data element from one Structure to another Structure within the main structure?

some guidelines would be appreciated.

Cheers

Pas.

Hi Pas,

it is not easy to understand when a change in DDIC is disruptive and when it is not. There are also small variations in the BRFplus code lines as BRFplus got more clever over time.

Do you know the ABAP report FDT_DDIC_BINDING_UP_TO_DATE? With the report you may check your application after doing a DDIC change. Then you can decide if you update BRFplus or revert the DDIC change.
