From Release 4.0A you can use SD credit checks in:
central financial accounting and decentralized sales processing.
The prerequisites to do so are as follows:
The sales organizations for the decentralized sales computer have to be assigned to different company codes. Therefore, there can be no higher- level company codes and each company code must be assigned to a separate credit control area.
The decentralized sales computers work independently with regard
to credit management. This means credit master files are
maintained, SD checks are made, and credit management releases are
all implemented decentrally.
Only credit relevant data from your sales computer are available at the order, delivery and goods issue stages. However, under some cirumstances you might need credit account data from the central system, (for example, total of open items, the oldest open item, maximum dunning level) and in that case Financial Accounting (FI) makes an A/R summary available.
The A/R summary collects FI data in the central system and uses distribution functions to send and evaluate it in the decentralized sales processing systems. The A/R summary is therefore a way of displaying FI information in a compressed form.
Because credit-relevant SD data (open order, delivery and billing values) are not distributed, there are certain prerequisites for working with distributed systems.
To work with distributed systems, one of the following requirements must be met:
You can set the age limit of the A/R summary in Customizing for Sales and Distribution under Basic functions --> Credit management/Risk management --> Credit management --> Define automatic credit control .
In the 'Checks in financial accounting/old A/R summary' field you can enter the permitted hours and days for the A/R summary's age limit. This is where you can determine until what age the A/R summary remains valid for a check. If the age limit of the A/R summary has been exceeded, then the document is blocked.
You can only make entries in the permitted days and hours fields, if you go to Customizing for Financial Accounting under Accounts Receivable and Accounts Payable --> Credit Management --> Credit Control Account --> Make basic settings for credit management
and enter X in the Read A/R summary field.
The A/R summary is either distributed periodically by the
central financial accounting system to the decentralized sales
computers, or, if the A/R summary is out of date, the system uses a
Remote Function Call to update it.
In order to reduce the workload on the system, SAP recommends that you proceed as follows:
If the A/R summary is out-of-date, the status of the credit data
is set as such in the sales document. The document is then blocked
and appears in the credit employee's worklist. You can determine
whether a warning appears, or whether the status is set for
out-of-date data for individual or named checks that require FI
data. To do so, go to Customizing for sales and distribution -->
automatic credit control.
If you are working with the A/R summary and wish to process out-of- date data, we recommend that you set a status.
