SAP B1 DI API problem within IIS only

[former_member344841]

Hello,

I have a problem with my WEB solution that some times it's crash when i execute a code of SAP B1, for example I'm using the following code to get the item price:

var itemPriceParams = (SAPbobsCOM.ItemPriceParams)company.GetCompanyService().GetDataInterface(CompanyServiceDataInterfaces.csdiItemPriceParams);
            itemPriceParams.CardCode = cardCode;
            itemPriceParams.ItemCode = itemCode;
            itemPriceParams.UoMEntry = uomEntry;
            itemPriceParams.Currency = currency;
            itemPriceParams.Date = deliveryDate;

            return (SAPbobsCOM.ItemPriceReturnParams)company.GetCompanyService().GetItemPrice(itemPriceParams);

The executions of this code crash the IIS and all user's will lose their sessions.

I tried to call the same function with SAME dll (I'm using SAPBusinessOneSDK.dll) and in windows application and it didn't crash.

In IIS i enabled the 32bit application, and i tried to put the identity of application pool as local system, still no success.

What could cause those kind of issues i tried a lot of solutions but with no success.

Thank you!

Dear Noor,

I have seen this more time with IIS.

I would advise you to separate the IIS application and the DI API part.

make a service that listens to a port and send your request from tjhe IIS application to that port and return the answer as XML.

Kind regards

Hello Noor,

You can try installing both 32 - 64 bit versions of the DI API to your IIS server. And also try creating both x86 and 64x version of your web service too.

I know this doesn't explain too much but I had a problem similar problem with IIS. Same code block that works in windows form application was failing in web application. I solved it by installing 32 Bit DI API.

Kind Regards,

Atilla

Hello Atilla,

I tried to install DI API 64 BIT on the web server, and i kept the 32 bit version installed.

At the beginning it didn't work, same crash occurred, but then i changed the application pool "Enable 32bit" to False then everything works correctly without crash WOOHAAAA .

Thank you Atilla.

Best Regards,

Noor
