Sage Line 50 Addpurch Utility
In Sage Line 50 V5, you could only produce remittances for the
supplier accounts you had set up in your Sage Line 50 program.
The information that appeared on your remittances was taken
from the supplier ledger.
In newer versions of Sage Line 50 you can produce remittances for suppliers
who do not have a corresponding supplier record. This allows
you to produce free-format cheques for one-off payments. To
enable you to produce free-format cheques, Sage Line 50 no
longer takes the information for remittances from the supplier
ledger. This means that you can produce remittances whether
there is a corresponding supplier record or not.
If you want to include additional information from your
supplier records on your remittances, for example bank sort
codes and account numbers, you should convert the layouts
you require using this utility.
Note: This utility is installed automatically into your
Sage Line 50 program directory when you install Sage
Line 50.
>> To use the Addpurch utility
1. Open a Command Prompt by clicking on to your Windows Start Button
selecting Run, then type the word COMMAND and click on to OK.
From the command prompt (for example, c:\windows\desktop>) type cd\ and
then press ENTER.
2. At the c:\> prompt type cd "Program Files\Sage Accounts\layouts"
and then press ENTER.
The prompt should now read c:\Program Files\Sage\Accounts\layouts
Note: If your Sage Line 50 program is installed in a different
directory replace the above instruction with your own directory
name. The directory path can be found within your program by
clicking on to Help and then About and choosing the System
Information Tab. Your layouts will be held on the same path
as your data directory.
3. Before you can convert your remittance layout you will
need to save this with a new filename. (maximum of 8 characters).
For example, to rename one of your existing layouts from
the c:\Program Files\Sage\Accounts\layouts prompt type:
copy remita4.sly newrema4.sly
and then press ENTER.

If all values for a specific "dummy" variable are identical, then you should delete the variable, because it adds NO information to your analysis.

If all values for one "dummy" variable MATCH the values for another "dummy" variable, then the two variables are 100% correlated -- remove one of them from your analysis.
