Are numericals accepted as Package names in HANA Studio ?

[babu_kilari4]

Hello HANA Modelling Experts,

I wanted to know if the numericals are accepted as package names ? I remember creating a package name with 00 in one of the openSAP courses in the past. I followed the same and system did accept it. However, I faced an issue while creating a .hdbdd file with the below syntax

namespace workshop.sessiona.00.models;

@Schema: 'WORKSHOPX_00'


context  tt_bp_addresses  {

  type PartnerId : String(10);
  type PartnerRole : String(3);
  type EmailAddress : String(255);
  type CompanyName: String(80);
  type AddressId : String(10);
  type City : String(40);
  type PostalCode  : String(10);
  type Street :   String(60);


};

System threw the following error while activating it.

workshop.sessiona.00.models:tt_bp_addresses.hdbdd
Syntax error: Unexpected token "00" at line 1, column 29

I tried escaping 00 as shown below, but it didn't help and I have got the following error.

workshop.sessiona.00.models:tt_bp_addresses.hdbdd
Syntax error: Unexpected token "\" at line 1, column 29

Can someone clarify if this is expected ?

Thanks & Best Regards,

Babu Kilari

Try putting quotes around the 00 like namespace workshop.sessiona."00".models;

You must be looking at an old version of the openSAP course because I started using g## as the package to avoid just such complications. It isn't that all numeric packages aren't supported, just that its a pain to remember to escape them.  That's why I would suggest adding a letter to the package name.

Thank you Thomas. That worked. Looks bit tricky. Yes - I was following the old course and I realized that there are two more updates ones. Interesting. Where can I find the latest documentation about this ? It would be helpful to take look at one central file which has all the necessary updated syntax and a sideline comment that refers to the old syntax.

Cheers,

We always update all the exercises when we do a new course. So although you might want to watch the videos from all the courses, you really only need to do the exercises from the latest:
