GR/IR

SAP中的GR/IR就是最主要的FI和MM对接中的一部分。涉及到vendor payment的问题也很多，特别是系统经常会block invoices，虽然系统有backgound jobs to release invoice. However, there are still some issues regarding releasing invoices. We have a quite few cases from users about why the system blocks invoices without reasons. We have the answer from SAP company about this. Basically they say our SAP version is quite low 4.5A. With higher version SAP, there are lots of enhancements. No wonder, that is why sometime we can't figure out what is going on with these blocked invoices. We have to release them manually.
But there are still a quire few reasons why invoices are blocked. But they are not obvious.
1: Sub-credit, if uses key in normal credit for sub credit. Then the invoice will be blocked with that credit because the quantity difference.
2: Good receipt is later than invoice received. This sometimes cause the price difference. Because GR doesn't carry price for goods. If the invoice is keyed in, the GR will follow the IR price. Maybe IR price is different with PO price. Then the system will block the invoice.
3:Check the good receipt date with IR date, maybe sometime, the background job hasn't been run to release blocked invoices.

SAP Archiving

这个星期二 公司的系统瘫痪了 在sm50里update process 都被占有了 没有人可以update，查看sm13 说是update deactivated，然后manually activate 了process，一会儿又停了，很奇怪都是supply officers 的process停了，重新启动了SAP 也是没有用，用DB02最后发现原来是mseg table满了 而且不能自动扩展了，最后只能table reorganize了 这都是因为没有做data archiving的原因
下面是SAP help link about data archiving

Add a printer at server level for SAP printer

For the example below I will use the printer name 'sap_XXX1'

The process is:

• Add the printer to /etc/hosts. Use the short form hostname, not a fqdn. Format is sap_ where is something meaningful to the customer, often geographic or site related with an index to map instances where the site has multiple printers which obviously is common. including any instance is usually specified by the customer.
• Test you can hit the printer using a ping or telnet if it’s a jetdirect or similar.
• remove any existing queues with the name you are using:

/opt/hpnpl/bin/removequeue -f -q sap_XXX1

• add the new queue:

/opt/hpnpl/bin/addqueue -i 3 -b off -q sap_XXX1 -h sap_XXX1

• test.
