These BAdIs are located in the Enhancement Spot /EDGE/EI_IT_ENH_SPOT_POSTING:
To enhance a block with new fields, there are three steps that need to be done.
- Enhance structure of the block
- Enhance BAdI /EDGE/BADI_EI_IT_GEN_SEL
- Enhance BAdI /EDGE/BADI_EI_IT_SAVE_BUTTON
- Enhance BAdI /EDGE/BADI_EI_IT_SCREEN
Enhance structure of the block
| Block | Structure |
|---|---|
| General Fields | /EDGE/EI_IT_GENERAL_DATA |
| FI Fields | /EDGE/EI_IT_FI_FIELDS |
| MM Fields | /EDGE/EI_IT_MM_FIELDS |
The structure has to be enhanced with an append that contains all the fields that want to be added.
Example:
General fields → s_bktxt
FI fields → xref1_hd
Enhance BAdI /EDGE/BADI_EI_IT_GEN_SEL
This BAdI has three methods, one for each block, to implement the values of the new fields.
- GET_DATA_GEN
- GET_DATA_FI
- GET_DATA_MM
It also has three enhancement screens:
This BAdI does not have an implementation so that, one implementation has to be done to be able to enhance a block.
Example:
Create implementation of BAdI:
Create a implementation class:
Create screen enhancements:
To be able to give value to the program and subscreen implementation and to the method in the class we need to create a function module with functions modules for the different blocks and the screens with the fields we want to add:
In each screen we need to add the new fields:
Moreover, a PBO module needs to be added in the PBO logic:
For the FI dynpro we need to retrieve the data for the FI fields:
For the MM dynpro we need to retrieve the data for the MM fields:
And for the general fields, we need to retrieve the general data for both structures (if both modules, MM and FI, are being enhanced):
Once the dynpros and the function group have been created, we can add them in the BAdI screen enhancement.
In the implementation class, the method need to be implemented calling to the function that set the values for each block:
In each function module we need to add the lines to ct_campos_pantalla with the required values from the dynpro that has been created:
The dynpros need to be type subscreen:
Enhance BAdI /EDGE/BADI_EI_IT_SAVE_BUTTON
This BadI is necessary to save the data of an invoice in database through the save button of the posting screen and to be able to retrieve it
The interface has three methods:
- FI_SAVE_BUTTON: Enhancement for SAVE button in posting screen FI.
- MM_SAVE_BUTTON: Enhancement for SAVE button in posting screen MM.
- GEN_SAVE_BUTTON: Enhancement for SAVE button in posting screen General Fields.
In these methods we need to enhance the changing parameter CS_STRUCTURE_GEN adding the new fields data to it, to be able to save it in data base and retrieve further on:
Enhance BAdI /EDGE/BADI_EI_IT_SCREEN
This BAdI is necessary to add new fields to the posting screen.
The interface has six methods:
- SET_HEADER_GENERAL
- SET_POSTING_FI_VENDOR
- SET_POSTING_FI_PAYMENT
- SET_POSTING_PO_VENDOR
- SET_POSTING_PO_PAYMENT
- GET_SCREEN_VALUES
If the ALVs for Document items, Tax positions or Logistic positions want to be enhancement, please check the indications for it in the next link: 2.2.2.5 ALV enhancements.
