How to create a custom TAB for MIGO Item Details
Dear all, I have implemented a custom tab in MIGO, you can follow the steps.
My requirement was to add a new tab named “Warranty” in MIGO.
Step1 : Create a custom table to store the data of “Warranty” tab
The first four fields should be the key fields, and the rest fields are your required custom fields.
Step 2: create a structure with the custom field you require on the MIGO.
Step 3: open structure GOITEM and append the same custom structure into it as shown below.
Step 4: Create another structure and append the table created in Step-1.
Step 5: Create a Table type of the structure created in step-4 as shown below.
Step 6: go to SE80 and create a program as shown below. This screen must contain two screen.
Step 7: SE19 -> Badi Name: MB_MIGO_BADI
Press Create Impl. Button and create Implementation: ZMIGO_WARRENTY as shown below.
Step 8: Create a Class : ZCLASS_MIGO_WARRENTY as shown below.
Step 9: Maintain the following attributes in your Class Interface as shown below.
Step 10: Write the following codes for the methods shown below.
(a) for IF_EX_MB_MIGO_BADI~INIT
METHOD if_ex_mb_migo_badi~init.
APPEND gf_class_id TO ct_init.ENDMETHOD.
(b) for IF_EX_MB_MIGO_BADI~PBO_DETAIL

ENDIF.

ENDIF.ENDMETHOD.
Note: Leave the other Methods blank. Do not write any thing in that.
Step 11: Open MIGO , you will be able to see the new tab “WARRANTY” as shown below.
The system will store the data of your custom screen into the table created in Step-1.
