HModifyStructure finds non-existing file

Hi,

did some tests of a running program. One of the involved restoring of backups. It doesn't work anymore, HModifyStructure finds a file which is named 0KUNDEN - where a file KUNDEN is in the analysis only. I did all the repairs possible, no success, 0KUNDEN is there and that one seems to point to the phyiscal file BACKPLUS2_KUNDEN.DAT which is a data file in fact. The logical file name is KUNDEN but not 0KUNDEN. The error message is:

Error at line 84 of Click Button1 process.
HModifyStructure function called.
Unable to access the file.
The description of <0KUNDEN> stored in the analysis is not compatible with the one of <C:\ProgramData\SysPredl\BackPlusV2\DATEN\BPLUS2_KUNDEN>.
The <KUMOTNORD> item of <0KUNDEN> file described in the analysis does not exist in the file.

----- Technical Information -----

Project : BackPlusV2

WL call:

What happened?
Unable to access the file.
The description of <0KUNDEN> stored in the analysis is not compatible with the one of <C:\ProgramData\SysPredl\BackPlusV2\DATEN\BPLUS2_KUNDEN>.
The <KUMOTNORD> item of <0KUNDEN> file described in the analysis does not exist in the file.

Placing an HListFile before HModifyStructure and showing the list of file shows as:

There is no file 0KUNDEN at all ...

Hi, there were several fCopyDir(..) some lines of code above the HModifyStructure(..) command. One of those fCopyDir(..) commands failed because the directory to copy simply wasn't there. However, it seemed to trigger this problem with HModifyStructure(..) .

Lesson learnt: always look whether a directory to be copied is existing and do the fCopyDir(..) only if it is existing ....
