COA Mask
Objectives
Overview
In this section, we will first define COA masks, and then learn how to set up and use them.
Finally, an exercise will let you practice your newly-acquired knowledge.
Definition
A COA mask is a matrix that defines the combinations of GL accounts, sub-accounts, cost centers, and projects to which you can post transactions.
Three COA element types have COA mask maintenance functions:
• Sub-Account Mask Create (25.3.9.1.1)
You specify a sub-account COA mask code and list the ranges of GL accounts with which sub-accounts assigned that COA mask can be combined.
• Cost Center Mask Create (25.3.9.2.1)
You specify a cost center COA mask code and list the ranges of GL accounts and sub-accounts with which cost centers assigned that COA mask can be combined.
• Project Mask Create (25.3.9.3.1)
You specify a project COA mask code and list the ranges of GL accounts, sub-accounts, and cost centers with which projects assigned that COA mask can be combined.
You assign a COA mask to an element using the COA Mask fields in Sub-Account Create/Modify, Cost Center Create/Modify, and Project Create/Modify. The COA mask code you specify must be of the same type as the COA element. One COA mask can be reused by many COA elements.
Important: When you change COA mask settings for a domain, you must log off the application and log on again for the changes to take effect.
COA masks are defined at domain level, and as part of a shared set. Three control fields in Domain Create (36.1.1.1.1) indicate which COA mask types are active: Sub-Account Mask, Cost Center Mask, and Project Mask. You can only define a COA mask if it has been activated in Domain Create. Postings will be validated for each of the types marked as active.
The system will also use the COA masks you define to restrict lookup values wherever account combinations are entered. For example, if sub-account COA masks are active and you create a journal entry posting line and specify the GL account, the sub-account lookup will only let you select from the sub-accounts that can be used with the GL account you specified.
