Infor LX & BPCS Tip: PowerLink

PowerLink is a Windows-based client for end-users within the Infor Development Framework (IDF). PowerLink allows exports/imports from/to the ERP database, but how much do you really know about it? Here is some helpful information about PowerLink.​

Why does PowerLink sometimes fail to export all records?
There's not a finite amount of records that PowerLink can export. However, PowerLink export was never intended to handle large volumes of data. It was designed as a quick snapshot of a fairly small subset and a simple view of the user's PowerLink card. 

What is the maximum amount of data that can be exported?
The maximum number of records is only limited by the system resource like memory, etc. When the system runs out of resources, an OutOfMemory error should occur. In previous testings, we have exported +1 million records, although the size of records differs greatly between business objects, the total size of the data could be an issue. For larger volumes of data, customers should investigate other tools such as the iSeries Access "Data Transfer from iSeries Server" feature to download directly to Excel.

How do I know if the size of the data is an issue?
1. When exporting to an external file (text, HTML) then importing to Excel: You can easily check the output (text, HTML) to see if the intermediate output has all the records. This can be done by visual inspection or through the use of column totals. Simply compare between the output and what you see in PowerLink. If the exported file has all the records, then the problem is definitely Excel.
2. When exporting to clipboard, then copy/paste to Excel: There is a clipboard export size limit that is controlled through client preferences. Check the exported data in the clipboard, and see if it contains all the records or only partial records due to the size limitation set in client preferences. If limited, change the client preferences using Customize from the Main browser > Preferences > Miscellaneous tab > Limit Clipboard Export, and try the export again. If the clipboard has all the records the problem is in Excel, which we don't have jurisdiction over.

Suggestions for improving the export process. 

  1. Reduce the number of columns seen in the view. This will serve to reduce the data being exported and may increase the number of records that can be exported. 
     
  2. Reduce the complexity of the view. If the view has one column that lives on a related object, then it has to build SQL behind the scenes to get that related record. If all of the columns come from a single business object, then the processing will be significantly faster.
     
  3. Export to HTML, which can be opened directly by Excel, Access, and many other programs. This reduces the processing of the export formatting because PowerLink needs only to put begin and end tags around each data element. This will also preserve column alignment when Excel or other programs open the file.
     
  4. Unless you are exporting a fairly small volume of data, export to a file, not clipboard. Clipboard is held in memory until the entire view is read, and records are written to the file as they are retrieved.

Tips:  LX | BPCS | M3

To utilize the Security Rules Optimization feature, a system administrator can assign security codes to 100 pre-defined user groups. User groups are created in the Group Security Maintenance (SYS603) program. All users assigned to this group possess the same level of security.   

A system administrator can assign security codes for up to 100 of the user groups. All user groups over 100 are still administered by all security reject/allow rules assigned to them but are not able to utilize the optimized process. 

Each of the security codes and access levels are assigned to user groups and are mapped to the account strings and stored in the Account Cross Reference (CEA106D1) file.   

Once security codes have been assigned, the system administrator must: 

  • Determine which level each group is allowed access.

  • Determine which segment values/account strings are assigned to which user groups.

  • Create security rules for specific segment values/account strings and assign these groups to the created rules.

  • Select the rules to be processed.  Processing can be done in either batch mode or interactively.

  • The Security Rules flag must be on in the CEA Control Parameters program before any rules are effective.

This feature provides a parameter that allows the user to enter expiration dates on the Inventory Transaction Posting screen, INV500, and Purchase Order Receipts screen, PUR5505, when they have received a lot controlled item that is not QMS controlled. This new field allows an expiration date to be entered and not overridden. A system parameter was added to Advanced Process Industries Parameters, API820D. When the parameter is set to Yes, a new lot expiration date is available in the Inventory Transaction Posting, INV500D2, and Purchase Order Receipts, PUR550D2, screens.
