Linking drop down boxes

Question

Hi all,
I would like to add multiple drop down boxes to my model, say f.e.:
- division
- country
- sales manager
- customer
These drop down boxes should be linked, such that when I select a value for division, the second drop down box only contains values that are applicable for division A. In our example, division A only sells products in Germany and Spain. When I select Germany, I would like the third drop down box to only show the names of sales manager from division A that sold products in Germany.
How to build this?
Best regards,
Ralph

Hi Ralph,
therefore you can write a simple ABAP RFC. Start the transaction SE80 and create a RFC function module.
If you use text in your infoobject ZDIVISION you can use a simple ABAP:
FUNCTION ZZ_GET_MD_ZDIVISION .
*"*"Lokale Schnittstelle:
*"  TABLES
*"      T_TABLE_VIEW STRUCTURE  /BIC/TZDVISION OPTIONAL
* For reading the data from the textable
SELECT * FROM /BIC/TZDVISION INTO CORRESPONDING FIELDS OF TABLE T_TABLE_VIEW.
ENDFUNCTION.
Then you can use a dynamic entry list and choose for the key F_BIC_DIVISION and TXTSH or TXTMD for your text.
Then you have to create your RFC function module for ZPRODUCT, this could look like:
FUNCTION ZZ_GET_MD_PRODUCT .
*"*"Lokale Schnittstelle:
*"  IMPORTING
*"     VALUE(I_SEARCH) TYPE  STRING OPTIONAL
*"  TABLES
*"      T_TABLE_VIEW STRUCTURE  /BIC/TZPROCUDT OPTIONAL
data: l_condition type string.
* Preparing String for SQL Statement e.g. A% for Division A
CONCATENATE '''' I_SEARCH '%' '''' INTO I_SEARCH.
CONCATENATE 'ZPRODUCT LIKE' I_SEARCH INTO l_condition SEPARATED BY SPACE.
* For reading the data from the textable
SELECT * FROM /BIC/TZPROCUDT INTO CORRESPONDING FIELDS OF TABLE T_TABLE_VIEW WHERE (l_condition).
ENDFUNCTION.
Then you create a dynamic entry list for ZPRODUCT and choose for input (I_SEARCH) the value of the divsion and for output again ZPRODUCT for the key and if you use text TXTMD or TXTSH for the texts.
Hope that helps,
Best Regards,
