## 13.3.5.2.3.4.1  Tab: Column Access (Infotype 5023)
On this tab page, you make the settings for access to columns within the (part) appraisal process. You specify display and change authorizations for elements in the appraisal template. You make the following settings:
- You specify the column owner of each separate column group. You can use an implementation of the BAdI HRHAP00\_COL\_OWNER to implement customer-specific column access.
- You specify who is authorized to perform which activities in each phase of the appraisal process and which columns are to be shown in the appraisal template.
You can only assign authorizations that are dependent on the various phases to either the column owner or all other participants involved in the appraisal process. You define who has authorization to execute an activity in a particular phase separately for column owners and all other participants. You can exclude the appraiser from the setting so that he or she has access in every phase (see example below).
You can define the following column access authorizations, for example:
- Free column access for all participants during the entire appraisal process This setting defines that all participants can display all part appraisals at any time and make changes to the appraisal document.
- Change or display authorization for column owners only.
This setting defines that only column owners can display a column or make changes in a specific appraisal phase.
- On this tab page you can use input help to define that columns are only to be visible to certain participants in the individual phases. To do this, choose the value Hide .
The infotype consists of:
- Checkbox: Default Use input help to select default entries for access authorizations. Click on the Default Access button to transfer the entries to the Column Access group box.
- Indicator: Changes
You can accept the transferred defaults without restriction or, if necessary, you can change entries in the individual cells. If you make and save any changes, the changed field is marked with an indicator. This makes it easier for you to identify whether these settings are default entries.
- Group box: Column Access In this group box, you make setting for column access.
##  Example
You depict a part appraisal process with one appraiser (manager), one appraisee (employee), and several part appraisers (colleagues). In the Part Appraisal column, the Part Appraisee (employee) is the default column owner. In the Part Appraisal phase, you assign the column owner change authorization and define that all other participants do not have access during this phase of the part appraisal.
In many cases, you might want the manager to have at least display authorization. You can assign the manager with the necessary authorizations (for example, Display for Appraiser , Hide for Others ) by using input help. This ensures that the column is not displayed for all other part appraisers and that the appraiser has display authorization for the part appraisal column.
##  Note
- The column access defined for the Part Appraisal (PAPP) and Final Appraisal (FAPP) columns is possible when one of the following columns is present in the appraisal template:
- In Process
- Completed
- Approved
- Rejected
- The Objective Setting (OBJ0) column comprises all objective setting columns (OBJ* and QBH*). The Part Appraisal (PAPP) column comprises the Part Appraisal Weighting (PWGT) and Part Appraisal (PAPP) columns. This is because the SAP system always processes the relevant columns simulataneously.
- If, for a particular phase, a user has Change access to the Objective Setting (OBJ0) column, he or she can use the Free Enhancement function. If this column is not present, the SAP sytem checks whether
the user has Change access to the Final Appraisal (FAPP) column for this phase. If this is the case, the user can use a Free Enhancement for this phase.
- The column access defined for the Part Appraisal (PAPP) and Final Appraisal (FAPP) columns is possible when one of the following columns is present in the appraisal template:
- In Process
- Completed
- Approved
- Rejected
You can use an implementation of the BAdI HRHAP00\_COL\_ACCESS to define customer-specific column access.
