Please describe the problem:
Users are unable to Get Transactions from (at least) Chase and Discover credit card accounts.

Quoting https://devel.aqbanking.de/trac/aqbanking/ticket/21:

It is an internal problem between GnuCash? and the bank server, or better put: The bank seems to have returned earlier the account number different from what it returns in response to a statement request now. So GnuCash? strictly scans the data returned (i.e. ImExporterContext?) for an account number which isn't to be found (because the bank returned another account number here, in some cases only the last 4 digits of it). 



Steps to reproduce:
1. Get Transactions from a Chase or Discover Credit card account.


Actual results:
Transactions fail to be imported.  Gnucash log reports:

    * 00:22:55  WARN <gnc.import.aqbanking> gnc_ab_gettrans: No accountinfo result for this account

Expected results:
The Reconcile dialog to appear for the account transaction importing.

Does this happen every time?
It happens consistently.

Other information:
This was initially filed with Aqbanking.  Martin Preuss (of Aqbanking) took a look at this and recommended the following solution:

I suggest that GnuCash? rather than calling AB_ImExporterContext_FindAccountInfo() scans the list of Accountinfos in the ImExporterContext? itself and assumes a match if the account number given in an Accountinfo is a substring of the real account number (the one GnuCash? is searching for).

So actually there is nothing that AqBanking? can do about it ATM.
