Dear Abapers,

In transaction MM02, under additional data, I want to disable the fields in the document data tab without affecting other tabs.There is a table control in that tab and I want to disable it making it only to display. Also, if I try to change the document and save, an error should be displayed saying this document cannot be changed.

I tried to find the badi's to do this and was helpless. Please suggest me some alternatives.

Hello Tharun,

if you wants to do before save you can use this badi.

IF_EX_BADI_MATERIAL_CHECK~CHECK_DATA.

Please elaborate your queries , that which type of data you wants to check in MM02.

And why not you are using SE24 , to know which BADI you need, if you don't know

the use of SE24 to find required badi, then please read the document first, then revert me.

i guess this can be achieved using configuration of field selection in material master check with the functional people...

Hi,

We maintain the materials using Vistex system as well. So, if a material is maintained in vistex and for the same material the document data is tried to change and save in mm02, then a error message should be given saying that changes cannot be made for vistex controlled materials. We shouldn't be allowed to delete the document data for this material as well.

I am checking with the badi which you mentioned. Will revert if it helps out.

Also, could you please tell me how to use SE24 to find the required badi. Like how did you find this badi? I usually find through the class cl_exithandler and this badi was not shown there.

Hi Tharun,

for Finding a required BADI, we use SE24 (Class Builder).

Follow these steps for finding required BADI for your use.

1. Go to SE24, put CL_EXITHANDLER in object type filled.

2. Press Display button.

3. A new screen will get opened, in this screen you will find a method named as

GET_INSTANCE

4. Double click the method, you will be on next screen, there is a method named as

CALL METHOD cl_exithandler=>get_class_name_by_interface

put a BREAK POINT on it

5. Run the standard transaction for which you have a requirement for finding BADI,

Double click on right hand side of exit_name, on successive pressing F8

you will get different BADI name for different screen for a standard transaction.

Do as mentioned, and find the required BADI for your use.

(While debugging you will get all BADI details)

CALL METHOD cl_exithandler=>get_class_name_by_interface

EXPORTING

instance = instance

IMPORTING

class_name = class_name

CHANGING

exit_name = exit_name. (double click here)

We can achieve this one by field selection for master data and we can do by using the Transaction variant by SHDB here we can restrict the fields what and all not require.

You should use method CHECK_DATA of BAdI BADI_MATERIAL_CHECK, but the error message may be raised a little late, and user will not be very happy to have wasted his time on this material reference. Nevertheless use this method which will always been called (e.g. from BAPI)

So you could also add your own implementation in an implicit ES of one of the PAI module of initial screen of transaction (like module IS_ENHANCEMENT_02 in include LMGMMIIS) so user would immediately be informed. (Don't forget to check t130m-aktyp and ok_code to not raise unecessary messages, e.g. MM03 transaction or function code not relative to maintaining data)

Raymond

Hi Raymond,

I am not aware of the implicit enhancements. Could you please elaborate how that is done. I have never worked with implicit enhancements before and so don't have idea about it.
