[Problem description]
When creating or modifying a cost center using transaction codes KS01/KS02, the screen does not display a code field, preventing the correct input of the company code, as shown in the image below. What could be the reason for this? How can it be resolved?
[Problem Analysis]
1. There are two types of relationships between control scopes and company codes:
① Multiple control scopes correspond to multiple company codes.
② A one-to-one relationship between a control scope and a company code.
The OKKP transaction code configuration in the backend shows the positional specification relationship as shown in the image below:
2. If the control range corresponds to multiple company codes, then the KS01/KS02 screen will display the company codes;
If the control range is paired with a company code one-to-one, then the KS01/KS02 screen will not display the company codes.
3. The control over the company code on the transaction code KS01/KS02 screen is determined by the following two program segments:
Program: LKMA1F20
Program LKMA1F00.
4. The `gd_one_bukrs` parameter in the program controls whether there is only one company code within the specified scope:
① `gd_one_bukrs = X`
Indicates there is only one company code, in which case the company code is not displayed.
② `gd_one_bukrs = empty`
Indicates there are multiple company codes, in which case the company codes are displayed.
5. The `gd_one_bukrs` parameter in the program is used to determine the number of company codes after the program reads the function `RK_BUKRS_OF_KOKRS`.
You can use transaction code SE37, input the function `RK_BUKRS_OF_KOKRS` point test, and then input the control range to see how many company codes are under the corresponding control range.
[Solution]
Method 1:
Use transaction code OKKP to check how many company codes are under control.
Method 2:
Use transaction code SE37 and the input function RK_BUKRS_OF_KOKRS point test to check how many company codes are under control.
